IMPROVEMENT IN CURTAIN-FIXTURES.

Specification forming part of Letters Patent No. 136,030, dated I`ebruary 18, 1&73.

the bracket; Fig. 4, a diagram of a portion of the bracket and ratchetto illustrate the operation; and in Fig. 5, a vertical section of thetwo parts of the pulley as prepared for attachment.

This invention relates to an improvement in the curtain-fixture patentedto L. L. Sawyer, July l1, 1871, theobject being to avoid the use of thepawl required in Sawyers patent; and it consists in the construction ofthe bracket with an elongated bearing, within which the pivot works, thesaid bracket constructed with a stationary stud, which, when atoneextreme of the elongated bearing, engages the ratchetwheel, the saidelongated bearing allowingk the drawing of the roll and ratchet so farfrom the said stud that the roll may revolve without the engagementbetween the stud and the ratchet; also, in combining with acurtain-tixture, a tube or cylinder to be set onto the ends of thecurtain-roll, so that the fixture, by means of the said tube, may besecured to the roll.

A is the bracket for the support of that end of the roll to which theadjusting mechanismk is attached, the bearing a for the pivot beingelongated about two diameters of the pivot, as seen in Figs. 1 and 3. Avertical slot, d, opens upward for the insertion of the pivot. On theend of the roll B apulley, C, is attached, and outside this pulley aratchet or toothed wheel, b, is arranged, the relative position of thistoothed wheel b to the bracketbein gl shown detached in Fig. 2. Iconstruct the bracket with a projecting stud, n, as seen in Figs. 3 and4.

The curtain D han ging upon the back side.

of the roll will hold the pivot back in the bearing, as seen in Fig. l,which is the position also seen in Fig. 4. In this position the teeth ofthe ratchet engage the projection'n, as seen in Fig. 1,which preventsthat from turning, and creates the friction to hold the curtain; butwhen the hand is applied to the cord E, which is around the pulley C,and drawn upon to cause the pulley and roll to re- -volve, the pivotwill roll back in the bearing to the position denoted in broken lines,Fig. 4, thus disengaging the teeth of the wheel from the projection a;and when the power which caused this operation is removed the weight ofthe curtain acting in the opposite direction will return the roll andpivot to the irst position and re-engage with the projection n.

In order to cheapen the construction of the pulley I form it lfrom twodisks, H H, see Fig. 5. These are struck up from sheet metal, theircentral portion depressed, as at lz., the outer surface of thisdepression forming the bottom of the groove, of which the disks form thesides. These two parts are united at the center either by an eyelet, asin Fig. 2, or by forming what corresponds to one of the disks to passthrough the perforation in the other disk, and be closed down upon theopposite side. v

In curtain-fixtures of this character several parts are necessary forthe attachment of the fixture to the rollthat is, either the parts whichgo to make up the Vmechanism or the pulley and several screws ofthecommon pnl` ley-iXtures-and a person often experiences difficulty inproperly applying such fixtures. to the roll. To avoid this diiiiculty Iattach the xture to a short piece of roll, L, of the standard diameterfor curtain-rolls, and set this into the end of a cylinder or tube, N,of sheet metal, this tube being se much ,longer than the piece L thatwhen the tube is set onto the end ot the roll proper it will serve tosecure the fixture to such roll proper, and thusprepared the lixture isready for market; and the person who applies the iixture has only to cutthe roll the required length and insert it into the open end of thecylinder N1 By preference I apply the xture forboth ends ofthe roll inthe same manner, and this 2, In combination with a curtain-fixturecyliudf-r and block are appicable alike to a adapted for rolls, the tubeN and block L, large majority of the curtain-fixtures. substantially asand for the purpose speciled.
